My Ballast System

[mtnsmith]

Anyone have a picture of the factory thru transom?

A pic inside or outside? If no one else posts one I could get one on here tomorrow.

A thru hull w/out a valve would be the same as a thru transom w/out valve right. A failure anywhere in the sys. would result in a water leak as the pumps will flow water when off (except reversable). So a valve of some kind would be a must.

I don't think they would be the same. As I said, if you have a failure with the transom through hull, you are safe if you get on plane because the transom hole will be out of the water (the same reason you can't fill on the fly). My question is whether you could get water to go through a non-scoop through hull mounted into the bottom of the boat while on plane?

If your failure were above the water line, it would be impossible to get water into the boat unless you had a bottom mount thru hull with a scoop, and were moving at the time. So when you say 'failure anywhere in the system' it really depends on where.

Just one more thing to think about. 90% of the time the transom thru hull would be ok for me as I can fill while waiting for the vehicle parker to get back to the ramp. Anything still has to be better than throwing the pumps over the side. Maybe i will do 2 thru transoms. Run 2 pumps to fill large surf sac and the other 2 for the from and starboard rear.

Install definately easier with the thru transom and no gate valve.

Really would like a true comparison of a stand still fill versus a scoop moving fill.

Oh that's funny!!!

With my inlet on the transom the tanks will fill if we are going at the slowest idle possible. Where we ride on the intercoastal there is a long no wake zone before we get to the canal we can ride in and I flip the switches when we enter the no wake zone and the tanks do fill as we are moving.

I haven't seen an 07 with ballast in person, but it looks kind of like the tanks couldn't be removed easily. Can they be taken out?

Oh!!!! are boats supposed to be easy to work on

With the scoop style through hull, the bags fill much faster when under way due to the water being forced in.

Interesting concept on the non-scoop through hull. The downside to going with the non-scoop is that fill times will be slower, and if you have a catastrophic failure at the manifold, or in the pumps, you will be sunk (literally). I guess that you could install a manual valve and always leave it open, just close it in the case of disaster downstream.

I have questions:

Would you still put it on the bottom of the boat, or at the transom?

Will it still fill decently when under way?

Where does the factory Tige system put the through hull?

I would put the "thru-hull" in the transom, I think it would still fill by pressure while moving if thru the bottom.

Tige puts it at about the mid-way of the exhaust outlet up the transom, I dont think it would fill on the fly at all but It might drain (siphon) w/out a checkvalve

I have always thought that putting it on the transom is stupid for that reason. But come to think about it, if you have the catastrophic failure spoken of above, all you have to do is keep moving to stop the water from coming in.

I would like the factory tanks in the rear, but don't want the factory system, can Tige do that?

I'll sell you my tanks if I decide to go with all bags.

The factory tige system in our boat has it in the transom. It will not fill underway unless we are going at a sloooooow idle, basically just in gear.

any difference in fill times with forced scoop against just the thru hull? Without the gate valve I shoud be able to do a 4 pump manifold. Frees up some room under there

[xpjim1]

1.5"
We have two ballast installs going on right now and I could take pictures and makes notes if needed for you guys if needed.

Pictures and notes would be good. Would like to see your thru hull. Do you put two fill and drain on the intergrated bow sacs or are your running 4 fatsacs?

Saving on the gate valve would be excellent. Do you just take a hose from the thru hull to the manifold? Much simpler idea.

I missed that somewhere I think Coach said somewhere that his were siphoning out underway though, but a simple checkvalve will stop that and a whole lot less complicated to do........KISS

Yes you will need to put a one-way valve on the fill lines to stop the water from flowing back out on take-off.

[lee]

Because there is no forced induction while under way right right???? I see said the blind man.

At one time we used a 1.5" scoop thru-hull like Rival and with a scoop a gate valve was necessary to stop the tank/bag from filling at all times. With the scoop you would not have to turn the pumps on, just take off and the bags would fill.
